A couple of weeks ago I had to stop at a train crossing, arrived just a few seconds late to beat the train. It was a very long train. Then I noticed it was slowing down. As it got within one car of passing the intersection it stopped completely. A guy jumped off and did some stuff, then jumped back on. And the train started moving again - in reverse! I wasn't timing how long I was stopped, but it seemed like forever.
